This invention relates to turnover means useful In connection with automatic apparratus for cooking articles such as doughnuts and the like in hot cooking liquor; and'it has reference more particularl to turnover de-- the'articles are;

vices for apparatus wherem cooked by-flotation.

The object of my invention is to provide a simple, reliable and efficient means capable of turning the doughnuts over after they have been progressed through a portion of the apparatus afloat on one of their sidesnalsection, a portion of an automatic doughnut cookin apparatus with turnover means convenientfy embodying my invention in one form; an

Fig. II is a view similar to Fig. Ishowing a modification of my'invention.

Referring first 'to Fig. I of tions, the numeral 5 designates an elongated cooking. receptacle which is keptfilled with the cooking li nor to the level L, and in which the doug uts designated by the letter D are continuously progressed afloat'in the direction of the. arrow, by suitable means not shown. Either gas or electric means (not shown) may be employed to maintain the liquor L at the proper cookingtem erature in a manner known to those skille in the cooking arts.

To invert'the doughnuts after they have been progressed along substantially half the length of the receptacle 5 afloat on one of their sides in the liquor L, I provide a turnover means which includes an inclined endless belt 6. This belt is trained about pulleys or rollers 7, 8 secured on shafts 9, 10, and is v driven in thedirection indicated at a surface speed corresponding to the rate of prossion of the den hnuts in the apparatus,

depressing belt 6, a conventionally indicated- -electric heating device 11 functions to set up an upward current inthe liquor L as indicated by the arrowed lines in the drawings. If desired or found more convenient in practice, angeother type of heating device may of course employed, for example, a gas burner beneath the receptacle, with maintenance of a hot spot to induce localized upward circulation of the liquid at the desired "region. In the operation of the apparatus, the doughnuts D are progressed slowly but continuously from the right hand end of the receptacle 5 afloat on one of their sides, and, in encountering the lower run of the belt 6,

are depressed in the liquor against their buo ancy for a shortdistance of travel along t e receptacle. As the doughnuts are released from the submerged end of the belt 6 passing around the pulley 8, their forward ends are projected into the path of the upward current of liquor set up by the auxiliary heating means 11. Asa result, the doughnuts are turned over in the manner indicated by the curved arrow in the drawings incident to rising to the surface of the liquor L, and float on their other sides during progression in the liquor along the remaining half of the receptacle.

In the modification shown in FigHII, an upward current of the cooking liquor is 1nduced adjacent the delivery end of the belt 6a by a submerged spray nozzle 11a from which a jet of cooking liquor is dischargled. I

de v- The cooking liquor so discharged 1s ered to the nozzle 11a through a pi 13, by a pump I45 and said pump may raw the liquor throu h a pipe 15 leading either from the reoe tac e 5a, or from a separate source of supp as convenientpr desirable. shown, t e spra nozzle 11a dlscharges its jet. at an u war inclination toward a fixed deflector p ate '16 which is curved concentrically with-the axis of the belt roller 8a.

my invention, as the doughnuts are released. from the belt 6a, they are. turned over through cooperation of the nozzle 11a w1th the curved deflector plate 16 as shown by the arrow in Fig. II, incident to using to In the operation of the modified form ofthe surface of the cooking liquor L for subsequent flotation on their opposite or uncooked sides during further pro ession through the apparatus as in the rst de scribed embodiment.

Having thus described my invention, I claim: I 1. Turnover means useful with automatic apparatus for cooking articles such as doughnuts afloat in hot liquor, comprising means for temporarily depressing the articles against their buoyancy in the liquor incident to progression in the apparatus; and means for setting up an upward current in the liquor locally at the point of release of the articles by the depressing means to turn the articles over.

2. Turnover means useful with automatic apparatus for cooling articles such as doughnuts afloat in hot liquor, comprising means for temporarily depressing the articles against their buoyancy in the liquor incident to progression through the apparatus; and a heatin means at the region of release of the articles from the de ressing means for setting up a localize upward current in the liquor to turn over the doughnuts.

3. Turnover means useful with automatic apparatus for cooking articles such as doughnuts afloat in hot liquor, comprising an inclined endless belt for temporarily depressing the articles against them buoyancy 1n the cooking liquor incident to progression through the apparatus; and means for setting up an upward current in the liquor at the point of release of the articles by the depressing means to turn the doughnuts over.

4. Turnover means useful with automatic apparatus for cooking articles such as doughnuts afloat in hot liquor, comprising means for temporarily depressing the articles against their buoyancy in the liquor incident to progression through the apparatus; and a submerged nozzle for directing a jet of the cooking liquor upward against the articles to turn them over upon release by the depress' g means.

5. Turnover means seful with automatic apparatus for cooking articles such as doughnuts afloat in hot liquor, comprising means for temporarily depressing the art1- cles against their buoyancy in the liquor incident to progression through the apparatus; a deflector at the region of release of the articles by the depressmg means; and means for setting up a localized upward current in the liquor to cooperate with the deflector in turning the articles over.

6. Turnover means useful with automatic apparatus for cooking articles such as V doughnuts afloat in hot liquor comprising an inclined endless belt for temporarily depressing the articles against their buoyancy in the cooking liquor incident to pro ion through the apparatus; a curved eflector plate concentric with that end of the depressing belt from which the doughnuts are released; and means for setting up a localized upward current in the iquor to cooperate with the curved deflector plate aforesaid in turnng the articles over.
